guys i just put my headers in today, they both slipped in in like 5 minutes, anyways, after installing y pipe i noticed that on the drivers side the pacesetter y pipe is so close to the floor board! i mean i dont think i can even put my finger between it! i also installed the poly motor mounts, but is it normal for it to be so close like that to the floor board? i even loosened the headers and reinstalled them to try to get some more room between there

I know what you mean, we had to wrap high heat material around the gas lines that run right there too where the cat was on the Pacesetter/tsp catted y set up I just installed.

It's normal. Why? GM royally screwed us on room for the exhaust. If your not lowered you might be able to adjust it down a bit. The problem is there isn't much room to work with. On my car, the Y would need to be oval shaped to have decent clearance on the floorboard as well as the ground.

Yeah its normal for the Y to be close to the underside of the car. that is why many Y pipes have a flat pipe section on the driver side and why soo many people have problems with the Y hitting if they keep the stock Motor mounts.

thank god i did the motor mounts, i started and drove the car today after LT's and poly mounts, im surprised it dident bang with that little clearance! but i have great ground clearance, better then my stock y pipe clearance, i do hear a very light rattle, i think the catback is either touching the torque arm or the catback is touching part of the panhard rod brace

It is prolly a heat shield by the rear end right next to the gas tank

o im sorry i meant the torque arm was not to far away from the y pipe when the suspension was loaded! so hopefully the torque arm doesent smack the y pipe, i think its that top bar above the panhard rod that may be touching, ill double check tho

After I got mine all welded up I just heated the y-pipe and bent it down maybe a half inch or so. It wouldnt knock when I was just driving but when I pushed on the gas say to pass someone the torque would push it into the floorboard. Nothin 10 min, a jack, and pry-bar wont fix :-)

i remember my stock y pipe scraped every time i came out my driveway, this y pipe doesent do that, but i was also being more carefull too! ok here are some quick pics i took, u can kinda see how close it gets to the floorboard, there was a part on the back where it gets close the the fuel line but i couldent get that with the car on the floor,
